Sainz’s con­cern

Car­los Sainz also ran with a Halo fit­ted, but had more con­cerns about the sys­tem. “My big­gest con­cern was vis­i­bil­ity, but it’s not ac­tu­ally a prob­lem,” said Sainz. “When you leave the pits you have this thing in the mid­dle which dis­turbs you a bit but at the end of the lap you don’t even no­tice it’s there. Prob­a­bly the big­gest con­cern and mar­gin for im­prove­ment is that get­ting in and out of the car is quite tricky at the moment. Ex­trac­tion is not easy.”
